“I had heard from another source that Berg has in his possession more than the Kenya grandmother audiotape”
That point alone is enough to keep this issue growing. Since his grandmother is a witness, his COLB [vault copy] is the only political solution to end speculation.
As for court problems, the voter is supposed to uphold the Constitution in the way he/she votes. I’ve always thought that would be the most likely route. Once the info comes out, Obama will lose political support.
It’s not his COLB that will end speculation. A COLB is a “poor cousin” to a Cetificate of Birth (birth certificate). A birth certificate is made immediately after the birth, while a COLB may be made years or decades later and contains less info. COLBs can be forged much more easily than BCs. That’s why, e. g., the State Dept. doesn’t accept COLBs for passport applicants.
